FORMULATION FACT 01

We formulate our All Bright C Serum with citrus oils Citrus Aurantium Dulcis (Orange) Peel Oil which imparts fragrance while diligently limiting furocoumarins -- natural citrus compounds that can cause skin irritation when exposed to UV light. As always, wear sunscreen as part of a daily healthy skin care regimen.

FORMULATION FACT 02

We chose naturally-derived phytic acid instead of ethylenediaminetetraacetic acid (EDTA) salts designed to improve stability and enhance preservation of our products. Manufacturing EDTA and its salts involves reacting ethylenediamine, a harmful substance associated with reproductive toxicity. Unfortunately, EDTA and its salts may contain trace amounts of this substance. EDTA and its salts are also persistent and can harm the environment.

FORMULATION FACT 03

You’ll never see “Parfum/Fragrance” among our ingredients – full ingredient transparency, always.

      Best ever!

      I’ve used this product for several years and will always have it in my skincare bag. It has kept my skin looking bright and dark spots at bay! Lightweight and effective. The best part is that it is a clean product! I use it daily in the morning.

      Love this serum!

      This is my favorite serum. I use it religiously. I love the smell, texture, and use it on my face, neck, and even the tops of my hands. Gives me a nice glow and helps keep my skin tone even.
